ENGR00296231 com.android.cts.usb.TestUsbTest#testUsbSerial failed

The case failed on the satement "adb serial" != "ro.serialno"
"adb serial" will read /sys/class/android_usb/android0/iSerial
"ro.serialno" will be set by passing "androidboot.serialno=" in bootargs
init.freescale.usb.rc will update the /sys/class/android_usb/android0/iSerial
from "ro.serialno"
Set the serialno to be as board's serial, which customer should customized it

ENGR00293946 SD:ESDHC/USDHC Fix command timeout after UHS-I tunning error

Got intermittent boot failure of android image from UHS-I SD card. The
MBR read is failed.

When doing the UHS-I tunning of sampling point, ESDHC may get some command
errors (CIE, CEBE or CCE) at incorrect sampling point. In this case,
current driver will return from the "esdhc_send_cmd" function immediately
with having host reset, which also gates off the SD clock automatically.
But the SD card remains in the status of sending tuning block data and
waits the clock. When the next new command is sent from host, the clock
enables the SD card to sending the tuning block and does not respond to
the new command.

Fix this issue by adding a delay before host reset. So the SD card can
output tunning block and turn to "tran" status. The tunning execute bit
"EXE_TUNE" also be cleaned after each tunning.

ENGR00293946 ARM:imx6 Add dynamical USDHC/ESDHC pads settings

Add a interface "board_mmc_io_switch" for ESDHC/USDHC to switch its
pads settings. The BSP which supports this feature must implement
this function.
Add it for all imx6 series boards.
